24. The onset of Pliocene – Early Pleistocene fluvial aggradation in the Southeastern Alpine Foreland (Velenje Basin, Slovenia) and its paleoenvironmental implicationsEva Mencin Gale, Petra Jamšek Rupnik, Naki Akçar, Marcus Christl, Christof Vockenhuber, Flavio S. Anselmetti, Andrej Šmuc, 2024, izvirni znanstveni članek Povzetek: In this study, we focused on the Pliocene–Early Pleistocene fluvial terraces in the Velenje Basin andreconstructed the morphostratigraphy, sedimentary depositional environment, provenance and age of the graveldeposits using geomorphological, sedimentological, petrographic and chronological analyses. Geomorphologicalmapping revealed the presence of two main river‐terrace groups. The terraces in the older terrace group are severelydegraded and preserved only as remnants capping high ground, while in contrast the younger group is betterpreserved. Detailed lithofacies analyses of four selected stratigraphic sections of the older terrace group show that thegravel was deposited in a meandering and wandering environment. The gravel consists of metamorphic, igneous,volcaniclastic, clastic and carbonate lithologies derived from the north, east and west from the Paka Rivercatchments. To determine the timing of deposition, we performed isochron‐burial dating using cosmogenic 26Al and10 Be. Our new age constraints date the deposition of the older terrace group to 2.7 ± 0.3 Ma. Establishing theaggradation and incision model of the Velenje Basin documents pronounced regional tectonic uplift during thePliocene–Early Pleistocene, which led to incision and the subsequent formation of a terrace staircase.

28. Report on economic justification of the project : LIFE Stop CyanoBloomMaja Zupančič Justin, Gorazd Lakovič, Tinkara Rozina, Bojan Sedmak, Marko Gerl, 2017, končno poročilo o rezultatih raziskav Povzetek: The Annexe 17 of the Final Report of the project LIFE Stop CyanoBloom, presenting the “Report on economic justification of the project” is composed of 14 chapters. The first part of the report gives a general overview of the cyanobacteria and their blooms, and species and toxicity of cyanobacterial toxins. With a literature review, economic consequences of cyanobacterial blooms on human health, commercial fishery, tourism and recreation, and lake monitoring and management have been evaluated. The chapter on phytoplankton and bacterioplankton monitoring options presents the importance of the phytoplankton for the lake ecology and evaluation of the water quality status. Traditional phytoplankton monitoring approaches are compared to the new monitoring options applied in the project. The chapter in-lake cyanobacterial control options give a broad review of available in-lake rehabilitation and remediation options, which can be compared with the electrochemical oxidation technique presented in the following chapter and applied in the project. According to the results obtained during the pilot testing activities, a cost evaluation of the approach has been performed and presented in the report. The last chapter gathers open issues and proposals for the further work in this field.

29. Recommendation for the unit of measurement and the measuring system to report traceable and comparable results expressing GM content in accordance with EU legislationPhilippe Corbisier, Dejan Štebih, 2017, končno poročilo o rezultatih raziskav Povzetek: It is important to guarantee that results expressing the GM content are reliable, comparable and fulfil the requirements of existing EU legislation. The use of different measurement units to express a GM content, the appearance of new analytical methods that do not require a calibrant and the composite EU legislation on GMOs have triggered the need for a document to clarify how to obtain reliable and comparable results.
For this guidance document, past and current EU legislations have been reviewed with a special emphasis on what is meant by 'GM percentage' in the different legal texts. The metrological traceability of measurement results and the currently available guidance are explained and summarised. The particular case of botanical impurities and the genetic constitution of GM seeds are described and illustrated to better understand the complexity hidden behind this type of analysis. An overview of the different analytical methods based on DNA measurements and used for the expression of quantitative GM content results is provided, including the use of new techniques based on digital PCR (dPCR).
A measuring system that allows for comparing results by making them traceable to the same reference system has been elaborated in detail. Needs and tools are described and a solution has been proposed to convert results expressing GM content to the required measurement unit, whenever this is needed.
By following these recommendations, results obtained in GM copy number per haploid genome equivalent (cp/HGE) by dPCR can be converted into mass fraction percentage and compared to the results obtained by quantitative PCR (qPCR) either with a calibrant certified for its GM mass fraction or with a calibrant certified for its GM purity.
The general principle is to relate a measurement result to a GM quantity embedded in a specified certified reference material (CRM) either directly or via one single conversion factor (CF) per event. This conversion factor and its related uncertainty need to be determined precisely for each CRM batch, preferably on the pure GM CRM (100 %), using, for example, dPCR. The estimated uncertainty associated with this conversion factor must be integrated into the measurement uncertainty of the final results expressed in GM mass fraction.
CF are currently not yet established for most CRMs. CF values have been recently reported in a few pioneer dPCR studies. However, such proof of concept studies remain incomplete. Therefore, to avoid a gap between new technologies and current EU regulation, the working group recommends to launch a dedicated study to determine CF values on CRMs. Such a study should involve a limited number of competent laboratories with a proven experience in dPCR. The study could be coordinated by the EURL-GMFF.

30. Protection study for Ulcinj Salina : final versionAndrej Sovinc, Davorin Tome, Michael Hošek, 2017, končno poročilo o rezultatih raziskav Povzetek: Ulcinj salina is situated in the outermost southern part of Montenegro and covers slightly less than 14.5 km2 of salty basins (total surface area is 1.477 ha). The salina is 1 km from the city of Ulcinj and from the Albanian border.
Ulcinj salina is located on the site of the former lagoon and wetland in the delta of the River Bojana. The works on amelioration of the former wetland area started in 1913. That is when the wetland was connected with the sea by the Port Milena channel and isolated itself from the Bojana River with a dike. In 1920 the decision to start with the establishment of the salina in Ulcinj was made. The salina was concluded in 1934 and the first harvesting of salt was done in 1935. The Ulcinj salina was created from the sea and represents a "cultural lagoon" and a man-made landscape. It is surrounded by channels that drain the nearby marshes and “knetas” (adjoining marshlands), not allowing their water to mix with the water from the salina. The channels take the water into the Port Milena canal and then into the sea.
The technological process of production was upgraded in the 1970s with construction of the refinery and with attempts to expand the production, both by enlarging the territory of the salina and use of industrial production between 1984 and 1994. Yearly production of salt before the above-mentioned attempts to expand the production (in the period 1935 to 1983) was highly dependent on the weather conditions and organisation of work; a maximum of 41.240 tons of salt was produced in 1952. A combination of manually collected salt and the salt produced through industrial process in the newly constructed factory in the years 1984 to 1994 led to a maximum yearly production of 59.353 tons. By contrast, the production in the last years of production (2003 to 2013) was dramatically lower, reaching on average only around 17.000 tons per year.
Ulcinj salina has very hot summers, moderately warm autumns and springs, and mild winters with temperatures only rarely below zero. On average, the most rain falls in autumn and winter, summers are two to three times more dry. Year-on-year and within years, changes in the amount of rain can be significant. Powerful pumps are essential for assuring constant water levels in basins which supports the maintenance of the ecological character of the area. The absence of salt production and consequent changes in water management have caused changes in water salinity, water regime and consequently changes in biodiversity.
